AWS Certified Data Analytics Specialty 2021 – Hands-On - Pig on EMR

The video tutorial explains Pig, a component of the Hadoop ecosystem, as an alternative to MapReduce. Pig uses a scripting language called Pig Latin, which simplifies the process of writing map and reduce steps with SQL-like syntax. Although Pig is an older technology, it remains relevant and is extensible with user-defined functions. The tutorial also covers Pig's integration with AWS, highlighting its ability to query data on S3 and load external scripts from Amazon S3. Overall, Pig provides a high-level abstraction for distributed data analysis.
